FAN5904  
Multi-Mode Buck Converter for GSM/EDGE, 3G/3.5G and 4G PAs  
Description  
Features  
The FAN5904 is a high-efficiency, low-noise, synchronous,  
step-down, DC-DC converter optimized for powering Radio  
Frequency (RF) Power Amplifiers (PAs) in handsets and  
other mobile applications. In High-Power Mode, GSM Tx  
power is enabled. In Low-Power Mode, up to 3.0 W is  
supported, enabling up to 29 dBm output power for 3G/3.5G  
and 4G platforms.

2.7 V to 5.5 V Input Voltage Range  
VOUT Range from 0.40 V to 3.50 V (or VIN)  
Single 470 nH Small Form Factor Inductor  
35 mΩ Integrated Bypass FET  
100% Duty Cycle for Low Dropout Operation  
Input Under-Voltage Lockout / Thermal Shutdown  
1.71 mm x 1.71 mm, 16-Bump, 0.4 mm Pitch WLCSP  
High Power PWM Mode  
The output voltage may be dynamically adjusted from  
0.40 V to 3.50 V, proportional to an analog input voltage  
VCON ranging from 0.16 V to 1.40 V, optimizing power-  
added efficiency. Fast transition times of less than 10 µs are  
achieved, allowing excellent inter-slot settling.  
o
Up to 95% Efficient Synchronous Operation in  
High POUT Conditions  
An integrated bypass FET is automatically enabled when  
the battery voltage and voltage drop across the DC-DC  
PMOS device are within a set voltage range of the desired  
output voltage (VOUT = VBAT - VPMOS - VBP_TH). This dynamic  
bypass feature enables the FAN5904 to support heavy load  
currents under the most stringent VSWR conditions while  
maintaining high efficiency and superior spectral  
performance. The bypass FET may also be enabled by  
providing a VCON voltage nominally greater than or equal  
to 1.5 V or by driving BPEN high.

Output current up to 2.3 A

.
.
Low Power Auto Mode  
Up to 95% Efficient Synchronous Operation at  
Higher POUT Conditions  
o
o
Output Current up to 1.2 A  
The FAN5904 operates in PWM Mode with a 6 MHz  
switching frequency in Low-Power Mode and at 3 MHz in  
High-Power Mode, which limits high-frequency spur levels.  
It uses a single, small form factor inductor of 470 nH. In  
addition, PFM operation is allowed in Low-Power Mode to  
improve efficiency at low load currents.

Power-Loop Settling  
o
6 MHz PWM Operation at High Power and PFM  
Operation at Low Power  
Bypass Mode  
o
Up to 3 A Load Current  
The FAN5904UC00X option allows PFM Mode only when  
VOUT is less than 1 V, while the FAN5904UC01X permits  
PFM Mode at higher voltages for applications that can  
tolerate larger output ripple and that demand optimal low-to-  
moderate load current efficiency.  
Applications  
.
Dynamic Supply Bias for Polar or Linear GSM/EDGE
